Ldh Isozymes

Three phenotypes of lactate dehydrogenase (LDH) isozymes were found in sera of sockeye salmon (Oncorhynchus nerka), presumably representing B′B′, B′B, and BB genotypes. No association was obvious between LDH phenotype of sera and sex or total body length.Of 1006 sera from Asian, Bristol Bay, and Gulf of Alaska stocks, 826 were B′B′ and 180 were B′B or BB. Of 591 sera from Washington and British Columbia stocks, 589 were B′B′ and 2 were B′B; both of the B-allele phenotypes were found in fish captured at the Skeena River in northern British Columbia. These findings suggested that LDH isozymes should be useful in studies on ocean distribution of sockeye salmon and in characterizing certain Asian and Alaskan sockeye salmon populations.

Annual mean body lengths of adult sockeye salmon (Oncorhynchus nerka) covary systematically from year to year in major northern and central British Columbia stocks (Nass River, Skeena River, and Rivers Inlet). These positive correlations are greatest between sexes within rivers, followed by age-classes among rivers. A common factor or factors affecting sockeye length in the North Pacific Ocean is suggested. The mean length of age 1.3 sockeye salmon but not age 1.2 sockeye caught annually in these B.C. fisheries was negatively correlated with the magnitude of Bristol Bay (western Alaska) sockeye catches. During the spring of maturation, age 1.3 sockeye from these B.C. stocks were further from their natal streams, and likely subject to more intense competition with Bristol Bay sockeye than age 1.2 sockeye. The pattern of annual marine growth measured from Skeena River sockeye scales collected during the 1960s provides additional evidence that the length of age 1.3 sockeye was related to Bristol Bay sockeye abundance in the year of maturation. No such correlation was evident in scales collected from age 1.2 sockeye. These results suggest that sockeye populations have more systematic distributions in the North Pacific Ocean than has been previously reported.

Population structure of sockeye salmon, Oncorhynchus nerka (Walbaum, 1792), from coastal lakes in British Columbia was determined from a survey of variation of 14 microsatellite loci, with approximately 6400 sockeye salmon analyzed from 40 populations. Populations from the Queen Charlotte Islands displayed fewer alleles per locus than did populations in other regions. Genetic differentiation among the populations surveyed was observed, with the mean FST for all loci being 0.077 (SD = 0.006). Differentiation among populations was approximately 13 times greater than annual variation within populations. Regional structuring of the populations surveyed was observed. The accuracy and precision of the estimated stock compositions generally increased as the number of observed alleles at the loci increased. Simulated mixed-stock samples generated from observed population frequencies in different regions suggested that variation at microsatellite loci provided reasonably accurate and precise estimates of stock composition for potential samples from marine or freshwater fisheries.

Indian Food

Basic components of predation processes are briefly reviewed and data on these components are presented for several native Indian food fisheries. Depensatory mortality emerges as a common effect of these fisheries, which supports findings of earlier workers on Skeena River sockeye salmon (Oncorhynchus nerka). Native food fisheries therefore operate like natural "Type II" predators, and descriptive equations are provided for use by salmon managers and modelers.Key words: fishermen as predators, native, Indian, food, fisheries, salmon, depensation
